On Wednesday, Nov 16, 2022 09:00 AM The HDF Group hosted a webinar on NeXpy. NeXpy is a GUI application designed to to facilitate creating, reading, visualizing, and manipulating data stored in HDF5 files. Although it was primarily designed to handle neutron and x-ray scattering stored using the NeXus format, most of its functionality is applicable to other types of scientific data stored in HDF5 files or even imported in a variety of formats....

HDF5 can be built using two build systems: the Autotools (since HDF5 1.0) and CMake (since HDF5 1.8.5). For a long time, the Autotools were better maintained and CMake was more of an "alternative" build system that we primarily used for handling Windows support (the legacy Visual Studio projects were removed in HDF5 1.8.11). This is no longer the case though—CMake support in HDF5 is (almost) as good as Autotools support and CMake, in general, is much more commonly used now than when we first introduced it. So why are we still hanging on to the legacy Autotools?...

When using HDF5 or HSDS you’ve likely benefited (even if you weren’t aware of it) caching features built into the software that can drastically improve performance. HSDS and h5pyd utilize caching to improve performance for service-based applications. In this post, we’ll do a quick review of how HDF5 library caching works and then dive into HSDS and h5pyd caching (with a brief discussion of web caching)....
